Not in the way that current "cuckolding" stories are, i.e., the typical "cuck chair" stuff on the softer end and up from there. Before, it was much more of a stag/vixen dynamic, where the hotwife was doing it as a thing to bring the husband and wife closer together, or at least as a way to excite both of them with the understanding that they'd reconnect later. To use a (poor) analogy, if earlier stuff had been mild bondage, newer stuff often strays well into CNC and sometimes straight up NC/R. Even the folks there for swinging/sharing/swapping level their hate at the newer "hard cuck" stories.
I think it started around 2005 with the ongoing (forever it seemed) hard cuck sagas of BobbiNobbi and XLeglover (both since run out of LW) but by far the biggest influence on LW readership was a influx around the same time of some VERY high quality authors all writing in the "Burn the bitch" genre I think of writers like Starstang06 ...then suddenly BTB became the highest score stories (they always were kind of but I don't consider DanielQSteele etc to be true BTB) and the "middle of the road" authors (think Ohio) became less visible. The "Cheating" genre got placed into two very opposing sides BTB and RAAC( Reconciliation at all costs) with no middle ground and the BTB tales morphed into weird secret agent CIA type things ....where bizarrely the most successful writers held court (Go figure THAT out) ..... between the Cheating, the Secret agents and the Hard Cucks the swingers (which frankly never were a bit part of LW) Sharers/Stag-Vixens (who used to be the mainstay) and the fence sitters all got pushed to the side. Now this is ONLY in scores ...the majority of actual stories posted are still in the milder end of the spectrum but they don't get the big views, comments,scores or 1 bombs. George Anderson has created another genre all by himself on top of this .... I liked it all better when it was alt.sex.stories or the Old BBS services like Rusty's where I think I actually enjoyied writing more. Loving Wives is a strange catergory ..... it's a minefield and the new DonnerBBQ style genre in E&V is probably a better fit for hotness for all the old stag vixen types anyway.
